1 <br /> uuuesns oes�RscoNsutwrs <br /> physical parameters including temperature, conductivity and Ph were measured and recorded <br /> through out the purge process. After the physical parameters had stabilized and a minimum of <br /> 3 well volumes had been removed, the wells were sampled <br />' Groundwater samples were collected using a decontaminated teflon bailer with a disposable <br /> nylon line The sample was carefully transferred from the bailer into the sample containers. <br /> After each container was filled, capped and labeled, the bottle was sealed into a ziplock baggie <br />' and placed into an insulated cooler with ice. A chain-of-custody form completed concurrently <br /> with sample collection was sealed with the samples dunng transport to the laboratory. <br /> Groundwater samples were scheduled for analysis of TPH-G and BTEX using EPA Methods <br />' 8015m and 8020. <br /> Equipment Decontamination <br /> I <br /> To reduce the potential for cross contamination, augers, sampling equipment, and other <br />' associated downhole equipment were steam cleaned before moving to each borehole. Rmsate <br /> from steam cleaning was contained onsite in 55-gallon drums. Sampling equipment was cleaned <br />' . between sampling intervals using a solution of Alconox detergent and tap water, followed by a <br /> double rinse with potable water and a final spray-nnse with deionized water <br /> Site Health and Safety <br />' All field work was performed in accordance with an approved site specific WESTON Health and <br /> Safety Plan. A HW instrument was used to monitor air quality in the work area. The field <br />' work was conducted in Level D personnel protection <br /> I <br /> I <br /> I <br /> I <br /> LIMOlEC185SANJ000L5A"WI— 1 A-3 29 Augm Y9" <br />
